Definitions
- This invention relates in general to communication systems and in particular to bridging talkgroups in communication systems.
- FIG. 1 is a system diagram of a communication system in accordance with the present invention.
- FIG. 2 is a more detailed block diagram of the communication subsystem of FIG. 1 in accordance with the present invention.
- FIG. 1 is a system diagram of a communication system in accordance with the present invention.
- Communication system 100 includes a plurality of communication devices 102 (which could be portable radios or mobile radios) operating within a first talk group communicating via a private network.
- the first talk group also includes a communication subsystem 104 having first and second communication units 106, 108 (here shown as two portable units but could also be mobile units as well).
- Subsystem 104 preferably includes a portable radio 106 having a public network device 108 electrically coupled thereto. The electrical coupling can be wired (as shown) or wireless.
- Public network device 108 can be an iDEN phone or other public network device that includes remote speaker microphone capability.
- the public network device 108 communicates via the public wireless network 116 to a third party having a cell phone 110 or a standard telephone 122 (through the wireless network 116, Public Switching Telephone Network 118 or Internet Protocol 120).
- a user of communication subsystem 104 can communicate with both the first talk group 102 via the private network and can also communicate with public communication devices 110, 122 via the public network.
- a second talk group 112 operating within a public network system receives information from first private talk group 102 through the public network.
- Second talkgroup 112 can be formed of portable radios and/or mobile radios.
- System 100 may further include a recording device 114 for recording information relayed amongst the various talk- groups.
- a user of subsystem 104 can also communicate directly with public and private groups at the same time by using the microphone located in the public network device 108 (to be shown in FIG. 2).
- the user pushes a push-to-talk (PTT) button (not shown) to communicate with the first talk group using the private network as well as a second talkgroup using the public network.
- PTT push-to-talk
- the user can speak into the microphone without a PTT press and likewise have the audio transferred to private network communication units via the private network as well as public communication units via the public network.
- FIG. 2 shows block diagram of the communication subsystem 104 operating in accordance with the present invention.
- Subsystem 104 includes private radio 106 including a receiver 208, a transmitter 212, and a speaker 216.
- Public radio 108 includes a transmitter 210, a receiver 214, a speaker 218, and a microphone 220.
- a control line 204 synchronizes and controls routing of audio between devices 106 and 108.
- an electrical link exists between private radio 106 and public radio 108 which as mentioned earlier can be wired or wireless.
- Private radio 106 receives audio from the private network system (from other private radios) at receiver 208 and ports the audio through electrical link 202 to the transmitter 210 and speaker 218 of public radio 108. The audio is played out at speaker 218. The audio is also transmitted through transmitter 210 to the public network system to its ultimate destination-cell phone, standard telephone, or public dispatch radio.
- public radio 108 receives audio from the public network system (from a cell home, standard telephone, or public dispatch radio) at receiver 214 and ports the audio through electrical link 206 to the transmitter 212 and speaker 216 of private radio 106.
- the audio is played out at speaker 216.
- the audio is also transmitted via transmitter 212 through the private network system to its ultimate destination—a private communication network device(s), such as a private radio talkgroup, for example.
- a private communication network device(s) such as a private radio talkgroup, for example.
- the audio can be recorded to maintain a record of information relayed between the various groups.
- the user can speak into the microphone 220 and communicate with both private and public talkgroups at the same time (i.e. simultaneously). Audio received at microphone 220 (whether through PTT or phone mode) is forwarded to transmitter 210 and electrical link 206. The audio is transmitted from transmitter 210 through the public network to public communication units. The audio ported over electrical link 206 goes to transmitter 212 of the private radio 106 for transmission through the private network system to private network communication units.
- public radio devices including cell phones, standard telephones, and dispatch radios operating on public network systems can now all communicate with private radio systems and vice versa. Calls can now be transmitted and responded to dynamically between public/private networks. Different operating modes of a public network radio can now be transferred to a private network radio device. For example, iDEN phones have talkgroup, private call, and interconnect call.
- the communication system formed in accordance with the present invention allows the private radios to advantageously use all three modes of operation, provided that the corresponding services are also available in the private network.
- audio can be relayed between private and public networks in both directions.
- a system formed in accordance with the present invention can take advantage of three-way calling to extend the private network capacity. Talkgroups are now dynamically tied together. Calls from dissimilar parties not associated with the same private radio network can now communicate with each other.
- the communication system 100 of the present invention includes, but is not limited to, the following capabilities: public interconnect to private talk groups; public talkgroups to private talk groups; public dispatch to private talkgroups; and public interconnect to private dispatch. These are just a few of the capabilities system 100. Bridging private dispatch/talkgroups to public cellular telephony is an important advantage in that the private radio networks dedicated to public service can now extend the number of users that can use the system. Conventional/trunked communication systems can now be bridged to public cellular systems as well. Improved efficiency and improved response times can be achieved with a system formed in accordance with the present invention.
